AMP-activated protein kinase in the brain

International Journal of Obesity volume 32, pages S42–S48 (2008)Cite this article

Abstract

Since its discovery as an important regulator of fuel utilization in the periphery, AMP-activated protein kinase (AMPK) has become a contender for many important cell-intrinsic and organismal roles regarding energy balance in the central nervous system. The challenge will be to delineate the mechanisms by which neuronal AMPK can respond to cellular energy requirements as well as whole body energy demands. Thus, under physiological conditions in the brain, hypothalamic AMPK responds to changes in energy balance/food intake, whereas under pathological conditions, AMPK responds globally in the brain to energy challenge. Modulation of fatty acid metabolism affects energy balance in a context-specific manner and may provide an insight into other mechanisms for selective activation or inhibition of AMPK activity for therapeutic applications.
